SYSTEM CONFIGURATIONS

The M600/6-24V is a flexible amplifier, well-
suited for a multitude of system configurations.
In this section, the most likely configurations are
explained in detail.
Once you have selected your desired
configuration, you can use the amplifier panel
drawing on pages 18 & 19 to mark the required
switch positions for easy reference.
BI AMPLIFIED SYSTEMS
Bi-amplified systems are defined as systems
in which separate amplifier channels drive low-
frequency (LF) and high-frequency (HF) speakers
and are separately filtered to send appropriate
frequency ranges to each speaker system.
The most common application of
bi-amplification is to drive a subwoofer
system from one or more amplifiers or
channels and component speakers from
separate amplifiers or channels.
The M600/6-24V is designed to work as the
only amplifier in a bi-amplified system.
Bi-Amplified System with the M600/6-24V
In this configuration, channels 5&6 of the
M600/6-24V will drive subwoofers (stereo 75W
x 2 at 4 ohms, 100W x 2 at 2 ohms, or bridged
200W x 1 at 4 ohms) with low-pass filtering.
Channels 1&2 and channels 3&4 will drive
component speakers in stereo (75W x 4 at 4 ohms
or 100W x 2 at 2 ohms) with high-pass filtering.
Input connection options for a bi-amplified system
with one M600/6-24V are as follows:
A) No User Adjustability:
Req uired: a basic source unit or processor
with one pair of stereo outputs.
Inp ut Connections: a single pair of stereo
source unit outputs is connected to
the "Ch 1" and "Ch 2" inputs of the
M600/6-24V. Then, select "2 ch." on the
M600/6-24V's "Input Mode" switch.
Res ult: the relative level of the LF and HF

channels will be fixed by the M600/6-
24V's "Input Sens." settings and will
not be user adjustable from the helm
(unless an optional HD-RLC is connected
the "Remote Level Control" port and
used as a subwoofer level control).
B) Fade Front vs. Rear with no Subwoofer
Level Control:
Req uired: a basic source unit or processor with
two pairs of stereo outputs.
Inp ut Connections: one pair of stereo source unit
outputs is connected to the "CH 1 (Left)" and
"CH 2 (Right)" inputs and the second pair
of stereo source unit outputs is connected to
the "CH 3 (Left)" and "CH 4 (Right)" inputs
of the M600/6-24V (select "4 Ch." on the
"Input Mode" switch in the "Channel 5 & 6
Controls" section).
Res ult: the relative level of the LF and HF
channels will be fixed by the M600/6-24V's
"Input Sens." settings and will not be user
adjustable from the helm, but the user will be
able to fade the signal from front to rear.
An optional HD-RLC can be connected the
"Remote Level Control" port and used as a
subwoofer level control, if desired.
C) Fade Subwoofer Level vs. HF Level:
Req uired: a basic source unit or processor with
two pairs of stereo outputs.
Inp ut Connections: the first stereo pair of source
unit outputs each split with a "Y-Adaptor"
allowing the left signal to be sent to the "CH 1
(Left)" and "CH 3 (Left)" inputs and the right
signal to be sent to the "CH 2 (Right)" and
"CH 4 (Right)" inputs of the M600/6-24V.
The second stereo pair of source unit outputs
is connected to the "CH 5 (Left)" and "CH 6
(Right)" inputs (select "6 Ch." on the "Input
Mode" switch).
Res ult: in this mode, the user has the ability to
fade or control the level of the LF channels
relative to the HF channels via the source
unit's fader control without exceeding the
maximum clean output level set by each
amplifier section's "Input Sens." controls.
